‘Synth Lines‘ draws horizontal lines across the chosen area (full screen, layers or depth) modulating its height according to the brightness of the pixel.
Inside the Editor.
It’s very simple, once installed, select the camera of the scene and add the component ‘Synth Lines‘.
When you add it you will see something like:
In the common zone (1) you can change the intensity of the effect with ‘Strength‘. You can also change ‘Mode‘ between ‘Screen’, ‘Layer’ and ‘Depth’. Later we will see how they work.
In the ‘Lines‘ area (2) you can change the effect lines.
- Count, number of lines [1, 200]. Default 100.
- Height of the lines [1, 10]. Default 2.
- Thickness of the lines [0.0, 1.0]. Default 0.2.
- Antialiasing. Improves the visual quality, but decreases performance. Default true.
The next area is ‘Image‘ (3), in which you can modify:
- Color blend operation, similar to those used in Photoshop. Default ‘Multiply‘.
- Coloring modes, to choose between: solid, color gradients and HUE gradients. Default ‘Solid’.
The ‘Color’ (4) area is used to modify color parameters and you must activate it (in the small circle near the label) to be able to use it. The same happens with the last area ‘Glow‘ (5). It is used to activate a Glow effect. May decrease performance.
Pressing at 6 will go to the online help and in the ‘Reset‘ button (7) some parameters will return to their default values.
I said that there are three different modes. The first one is ‘Screen‘ and is the one used by default. It makes the effect apply to the whole screen. Another mode is ‘Layer‘ and with it you can apply the effect only to the layers you want.
Simply select the layers you want and they will be the only ones in which the effect is applied. If you see any accuracy faults, you can adjust the sensitivity with ‘Depth threshold‘.
With ‘Depth‘ mode you can select the depth range in which you want the effect to occur. The range starts at the ‘Near‘ distance of the camera and reaches the distance ‘Far‘.
Both modes, ‘Layer‘ and ‘Depth‘, add a depth texture to the camera, and may not be available on some mobile platforms. You should also keep in mind that both modes depend on the ‘Far‘ parameter of your camera. If you use a ‘Far‘ too large (default is 1000), you may have precision problems, so I advise you to reduce it as much as possible.
All code is inside the namespace ‘Ibuprogames.SynthLinesAsset‘ and main component is ‘SynthLines‘. If ‘myCamera‘ is a valid camera and you want to add the effect, you should do something like:
using Ibuprogames.SynthLinesAsset; ... SynthLines synthLines = mycamera.gameObject.AddComponent<SynthLines>();
The whole code is well commented.
